9:58 a.m.
New options --build, --build-overwrite, and --build-no-overwrite
are added to commands pool-create/pool-create-as/pool-start.
Perhaps it's not that necessary to allow pool building for pool-start,
but it doesn't hurt to have them.
---
The documents of pool-build is not that correct, as the flags
--overwrite and --no-overwrite are also supported by disk backend,
but it will be a follow up patch, with fixing the documents
for the new options together.
